I like that vessel, Starfleet could have adopted that design to be used with Federation technology.
I think at the Battle of Procyron (ENT: Azati Prime) we had a glimpse of a Dauntless Class ship participating.
With the specs and sensor data that Voyager brought home, Starfleet easily could have made a replica of that ship, and if it's only for the looks.
I think it would be great as somekind of Excelsior Costume. (I really hate the Excelsiors looks)
I always thought that the T5 Excelsior needs some other styled ship costume, because i know many who like to fly it, but just as many hate it's appearance. So i thought that a costume which does have a completely different design could be just what that ship needs.
Btw. i like the looks of the Dauntless a lot.
Of course it had to be larger than in the show, i think about 2/3 of the lenght of the Excelsior would be sufficient, because it is much more compact and massive IMHO.
I just had another (good?) idea.
After testing the Galaxy -R, especially the Battle mode i thought that it would be nice to have a ship that permanently like this (of course a bit weaker fo the sake of balance.)
What about making the Dauntless similar to the Galaxy -R in battle mode?
Of course it has to be a bit weaker, but i think it would be fun to have something like a light, agile and fast tactical focused cruiser.
Yes, the Dauntless was not truly a Federation ship. Memory Alpha link for the ship itself.Link for the ship-class. It did appear in an episode of ENT, as mentioned above (also mentioned in ship-class link), but that was (lore reasoning) an alternate timeline and (technical reasoning) they were reusing a lot of other ship classes in that battle, including known ships of other races for the Sphere Builders (see the link for the specific episode).
Ya.... No, the Dauntless was a bad idea. Plus, the things, what, a third the size of an Intrepid? What would it be? Its tiny, lightly armed and armored, (did it even HAVE weapons) and not even originally federation. I seriously doubt such a ship would be copied and used by the federation.
